They're making Yakuza 6! Of course, they are! And the latest numbered entry in the Yakuza series is PS4 only.
That shouldn't come as a surprise as other Yakuza titles are PlayStation exclusives. Sega didn't show any footage of the game, but expect to see tough dudes punching each other in the face.
Yakuza 6 will hit Japan in Fall 2016. And outside Japan? Someday, maybe. Someday.
